A multifunctional support, which consists of a high purity, 60 A, spherical silica substrate that has been bonded with cationic exchanger, sulfonic acid functionality in addition to a conventional reversed phase C8 functionality.

A reverse packing made by coating a thin layer of polybutadiene on to a spherical porous zirconia particles, 3 to 10µm.

Zirchrom PBD

L50

Multifunctional resin with reversed-phase retention and strong anion-exchange fuonctionalities. The resin consists of ethylvinylbenzene, 55% cross-linked divinylbenzene copolymer, 3 to 15µm in diameter, and surface area not less than 350 m2 per g. substrate is coated with quaternary ammonium functionalised latex particles consisting of styrene cross-linked with divinylbenzene.

Packing having the capacity to separate proteins by molecular weight over the range of 10 to 500kDa. It is spherical (10µm), silica based, and processed to provide hydrophilic characteristics and pH stability
